Sinus rhythm with multifocal PVCs and non-conducted P waves
Sinus rhythm with multifocal PVCs and non-conducted P waves. The rhythm begins as sinus rhythm, complexes 1 - 6. A multifocal couplet makes up complexes 7 and 8. This is followed by a brief pause. Next is a 4 beat run of polymorphic VT. A P wave is seen before the first PVC of the run and in between the 10th and 11th complexes. A nonconducted PAC follows the last complex of the run (12th complex). This is followed by a period of arrest. Another nonconducted P wave is seen during the period of arrest. A nonconducted PAC occurs after the 14th complex.
